@tectron yes, I had the same thing happen. It took a while to realize that it did not happen with HDMI disconnected which means that the power line in the HDMI cable is back feeding to power the led. I'm not 100% sure exactly how it's happening but I'm fairly certain that besides the led glowing very faintly it has no other ill effects.
I have the same issue on my nespi.
I had the same issue, too.
Editing the /boot/config.txt and setting config_hdmi_boost=1 solved the problem. ;) -
I've ran into an issue. The mosfet is set to off. I've checked to make sure none of my solder is being shorted. Whenever I plug the power into the NES Pi case slot regardless if the power switch is pushed in or not it will power the system and the pi. If I push the power switch in, it does nothing but if I push it out again it will shutdown the pi but the fans and lights will stay on. Not sure what to do. Is it possible I blew the cap or a diode?

Did you perform the hardware test? -
@yahmez
I did, when I take the on part from the mosfet and put it on the positive pin on the fan even with the power switch not pushed in it still powers on. I then push the power in button and leave it go for a few seconds and then turn off the power button and the light stays on its been on for the past minute or two that I've been typing this -
@ilackiq then it's a hardware issue. Things to verify: Diodes are in the correct orientation, bottom of gpio pins on the pi are not pushed through the insulation on the wires coming from the mosfet board. Check your work to completely verify that everything is soldered correctly. By far though the most common issue is that people do not completely cut through the traces on the PCB as shown in the guide. If these traces are not completely severed (no copper) then you will have this kind of issue.

https://i.imgur.com/YygmAy3.jpgThe diodes are facing the right ways, to make sure the mosfet or the switch board that I soldered to doesn't get shorted out by the USB/Ethernet board above it put electrical tape on them and I made sure it didn't make any pins/wires touch each other. I included a picture what how I cut the traces.
-
@ilackiq I'd be willing to bet that the traces are still connected, although you can not really tell one way or the other from your photo. Did you take photos of everything without all the tape on it? I can't really give any advice beyond what I have without seeing everything.

Album for them all -
Why is your orange cable connected to +5V of the fan?

What are you talking about? The only orange cable I used was connecting the two + pins on the switch board. There is another cable that looks orangesh-brown that I used to connect the switch board to the mosfet.

Oh that was the hardware test. It's been removed
-
@ilackiq try removing the pi completely. Nothing connected. Make sure the power switch is off, then plug in the power to the back of the case. Does the led come on?

My reset button is isolated and NESPi turns on and off fine. Reset button is on GPIO 5 and grounded. After I installed the shutdown.py script (curl...|bash), my Retropie boots to the 4 raspberries and then shuts down. I tried to get it to boot in safe mode but can't get to a CLI. Any help is appreciated, thanks.
-
It was the wrong shutdown script that caused the shutdown on startup.

@druz it is possible to replace the mosfet tcp8114 with another one more easy to find, actually I live in dominican republic here is really rare to find these spesific part, can you please help me
-
@elvycoll Consider to buy a NESPi+ case
Maybe you can buy a Pimoroni SHIM instead...
